The Megastructure is vast and infinite. The physical manifestation of the Netsphere, gone rogue. Time doesn't exist in an Utopia, where production technology has reached perfection with Nanotechnology and AI, even if the utopia has become a dystopia, or more accurately, a wasteland.

But of an scale which defies comprehension, even non-human comprehension.

And nonhumans they are, posthumans, parahumans. Silicon runs through their blood, and with the slender beauty of dark angels they wander the infinite volume of technological prowess.

Eternal solitude of a lost warrior. Fleeting serenity on beholding the accidental beauty of a million lost worlds.

......

The scientist and the warrior no force of nature (or beyond) shall stop them.
